VEHICLE-BRAKE.v

SPECIFICATION forming part of Letters Patent No. 732,783, dated July 7, 1903. Application tiled October 13, 1902. Serial No. 127,105. (No model.)

To @ZZ whom t may concern.-

Be it known that l, JOHN W. ROWE, a citizen of the United States, residing at Centertown, in .the county of Ohio and State of Kentucky, have invented certain new and useful Improvements in Vehicle-Brakes; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in automatic wagonbrakes; and it has for its objects, among others,to provide a simple and cheap construction of brake ot' this character which is entirely independent of the wagon -body and which can be readily adjusted to suit any required length.

A further object is to provide such a formof brake that will always be out of the way of the load `and the parts so disposed that l when either one of a draft-team pulls enough to move the unloaded wagon it will remove the brake-shoes from the wheels. By my construction should the load getagainst the brace in front of the Wagon and spring it either forward or to either side it will not in any wise affect the working of the brake. The load cannot interfere with the perfect working of the brake, as I make the brace of spring-steel, and the staff of the cog-wheel does not extend farther back of the brace, and the staff of said cog-wheel is provided with a toggle-joint or universal coupling. The draft of the load is not upon any part of the brake, but on the wrench-pin, which remains in front of the doubletree, and hence the brake is as easy to throw olf or on when the team is pulling as when it is standing still. The tongue can be easily removed when desired.

Other objects and advantages ofthe invention will hereinafter appear, and the novel features thereofwill be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a bottom plan of my improved brake. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a vertical transversesection through the rear hounds. Fig. 4 is a vertical transverse section through the forward portion of the front hounds. Fig. 5 is a perspective detail of one form of operating means for the sta of the gear-wheel. Fig. 6 is a detail showing the connection of the sta of the gear-Wheel. Fig. 7 is an enlarged vertical section through the front part of the hounds and the parts carried thereby.

Like numerals of reference indicate like parts throughout the several views.

Referring now to the details of the drawings, l designates the rear axle, and 2 the front axle.

3 designates the rear hounds, of ordinary construction, and 4 is the-reach or couplingpole, disposed in the usual manner, with its rear end slidably mounted in a recess 5 in the rear axle and -beneath the rear bolster 6. The forward endsA of the rear hounds are connected by the metallic strap `7, whichprovides a space within which the reach or coupling-pole 4 is received and guided. The reach or coupling-pole 4 is provided with a plurality of vertical openings 8 for the reception of a removable pin 9, which passes through the metallic plate 7 and is designed to hold the reach or coupling-pole in its adjusted position in a well-known manner.

The forward end of the coupling-pole 4 is disposed between the front axle and the front bolster 10 upon the king-bolt or wrench-bolt 11 in the usual manner. A bar 12 is shown in this instance as secured to the front hounds in vertical alinement with the front axle and through which the king-bolt 11 passes and upon which the front bolster lO is mounted. The coupling-pole or reach 4 is guided between the front end and its connection with the rear hounds upon the curved connecting portion 13 of the front hounds, as clearly shown.

14 is the brake-beam, carrying at its opposite ends the brake-shoes 15, adapted to engage the peripheries of the rear wheels, and this brake-beam is mounted for movement in the direction of the length of the couplingbar and is supported in the following manner:

IOO

16 is a transverse bar secured to the top of i the rear hounds and is provided upon its upper face with a longitudinal groove 17, in which is seated the bar 18, held in any suitable manner, so as to rock therein, and this bar has the vertical depending portions 19, which extend down upon opposite ends of the bar 16 and are secured to the brake-beam in any suitable manner.

20 designates braces secured at their rear ends to the under sides of the rear hounds and extended beyond the bar16 beneath the same and are provided upon their under sid es with elongated loops or analogous devices 2l, which receive and guide the brakebea1n 14.

22 designates coil-springs having their forward ends attached to suitable means, as the clips 23, which embrace the brake-beam, and at their rear ends connected with bolts 24, mounted in the rear axle and provided With adjusting-nuts 25, whereby the tension of the springs may be readily adjusted. These nuts are preferably handle-nuts, whereby the tension of the springs can be readily adjusted without the employment of a wrench.

The clips 23 are made adjustable lengthwise of the brake-beam, so they may be moved either way thereon, the beam being provided with a plurality of holes 26 for this purpose to receive the movable pins 27. The bolt-s 24 may be likewise adjusted in the hind axle by providing the latter with a series of holes therefor, as is shown.

28 designates levers pivotally mounted on their outer ends upon the braces 20, as shown at 29, in this instance being shown as pivoted upon the front vertical portions of the loops 2l. These levers are halved at their adjacent ends and overlapped, andthe overlapped portions are provided with elongated slots 30, in which works ,the pin 31, upon which is pivotally mounted the clip or analogousdevice 32. The levers 28 are provided between their ends with a plurality of holes 33 to provide for the adjustment of the clips 34, which are removably secured thereon by means of the pins 35 engaging in the proper hole 33, and these clips are connected with the clips 23 by any suitable pivotal connection, as shown.

From the above description it will be seen that the lever power can bereadily regulated as occasion may require.l It will be noted that the brake-beam, while being mounted to rock on its support above described, is normally held rearward by the action of the springs connected therewith.

36 is an extension-bar of any suitable construction, connected With the clip or clevis which connects the adjacent ends of the levers 2S, and this bar or rod extends beneath the portion 13 of the front hounds and serves to keep the same from dropping too low. This extension-bar has at the end nearest to said levers a series of links 37 of the same length as the distance from one' hole to another in the coupling-pole or reach, so as to provide for lengthening of said extension-bar to suit. any length of wagon-coupling. This extension-bar is held in line with and at proper distance from the coupling pole or rod by means of guide or eye 37 on the lower end of the bolt 38, held in said coupling-pole or reach and dependent therefrom, as shown, these bolts being held in the coupling-pole or reach so as not to turn therein. This extensionbar has at its forward end a link 39 for the king-pin to work through and to hold the extension-bar in place when the wagon is turning. The eye or thimble 39X at the front end of the coupling-pole serves to hold this coupling-pole up oft of the link, and there is a staple 40 in the front axle to keep said long link from working down under said eye or cuff. The extensiolrbar has a cog-piece or rack 4l, which works under the doubletree and which is adapted to engage with the cogwheel 42, which will soon be described. The extension-bar has in front of the said rack-bar a coiled spring 42', which spring has a bar 43 extending within the same, as shown. This spring is fastened at its other end on the tongue 44 in any suitable manner, so it can be taken up or let out when desired. This spring is for the purpose of helping the team to pull the brake'shoes oi of the wheels. This admits of the springs at the rear of the brakebeam being as strong us desired, and yet require but little draft at the doubletree to relieve the wheels of the brake-shoes. This bar is stapled to the tongue, so as to move back and forth thereon, and is provided with a stop-shoulder 45 to raise the bar. The lever 46 has a bar secured to its front end, that reaches to the end of the tongue, and to it the tongue-chains are secured. The rear end of this lever is stapled to the tongue. Under the front end of the lever there is a small spring 47 to raise said end of the lever above the level when the bar 43 in the spring 42 is drawn olf of said lever. rlhis lever is for the purpose of throwing off the power of the spring 42' when the springs 22, connected with the brake-beam, have drawn the bar in said spring off of the lever. Then the team holds back on the tongue-chains, and said lever will come in contact with said bar, and the full power of the springs 22 takes effect on the wheels 48 is a stop bolted to the front hounds at a proper place to serve as a stop for the doubletree 49. This stop also serves as a brace for the hounds and "answers the purpose of staychains. This stop is of substantially the same length as the doubletree, and therefore enables either one of a draft-team to relieve the wheels of the brake-shoes.

50 is a b race extending across the front end ofthe front hounds, to which it is secured,and it is provided in its under face with a notch or recess 5l in which the extension-bar is free to move. This brace-bar 50 serves in addition to bracing the front ends of the hounds as a stop to prevent the tongue from rising too high.

52 is a metallic brace connecting the front and rear brace-bars of the hounds. It is provided with a slot 53, extending lengthwise IOO IOS

ITO

thereof,` in which works a pin 54 on the doubletree, and with another slot 55, in which works the statt of the-cogwheel. Between these slots it is provided with a hole 56, in which is mounted the wrench-pin 57. The pin in the doubletree is for the purpose of holding the slide that Works on the stai of the -cog-wheel and to keep the doubletree from slipping .endwise Projecting from the under side ot' the tree are the bolts or pins 58 for the purpose of holding the end of the rack or cog-piece on the eXtensionLbar to its place and also to prevent it from working too far backward and forward. "1`he singletrees are attached tothe doubletree, so they cannot drop down and rub the front-wheel.

The cog-wheel 42 is disposed in front ot' the doubletree and is held a proper distance from the doubletree by two slides 59, disposed one above and the other below the same. and which are engaged over the staff of the cog- Wheel and working on the boltextending upward from the doubletree. n These pieces are slotted to receive the wrench-pin. The cogwheel staff 60has aball-and-socket connection with the cog-wheel, and this staff is made rectangular in form for the said universal joint. The cog-wheel is held -in engagement with the cog-piece or rack by means of the bolt 6l, which projects downward from the ear 62 and engaged with the ear 63, said ears being carried by the ianges of the cog-Wheel or by the hub thereof, this bolt in connection with the iianges of the cog-wheel serving as a guide in which the rack moves and by which it is held in engagement with the cogwheel. The cog-wheel statt is provided with an extension 64 for the purpose of lengthening the statt ot' the cog-wheel as may be del sired. The cog-wheel is designed to be rotated by a crank 65, secured on the top ot' the extension-statt and an extension-brace 66, the upper portion thereof being in the form ot a long fiat hollow piece with a square crook at the top, with a hole in the center to receive the extension-statt and small catchslits 67 around its edge to receive the catch or pawl 68, carried by the crank. This serves the purpose of holding the cog-wheei and rack-bar in any position desired.A This provides for the throwing oft' of the brake to back the wagon and to throw on the brakeswhen desired, so that the draft-team cannot pull the same off. It also provides for the raising of the crank to suit any height of load.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
